They say the effect varies by person, but lasts 3-6 months. They said the effect appears within 2 weeks after getting it, and that it does not magically stop sweating completely after getting it; if you originally sweat a lot, you sweat less, and if you did not sweat much, you may not sweat.
I was ready to grab the doctor by the collar because I thought it would hurt, but maybe because they numbed it for a long time, it did not hurt at all,,, it was okay! (I think it was not much different from underarm laser hair removal!)
After getting it, intense exercise is prohibited for a week and alcohol is prohibited the next day, but yesterday I just went for it and poured down wine, and nothing happened.
